Al2O3 Ceramic Lined Pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface.
Ceramics with very low friction factor at low impingement angles decreases the abrasion of materials maximally.
Its low density makes it easy to carry and install. Furthermore, its diamond-like hardness, fine grain structure and superior mechanical strength are the unique features that make it a wide range of demanding applications, such as coal preparation, power generation, iron and steel making, cement, asphalt, dredging, mining and mineral processing, oil and gas drilling.
The Ceramic Tiles could protect Industrial Components against abrasion, impact wear and high temperature of above 1000C. Standard Flat Tiles of Square & Rectangular Shape having thickness of 6 to 50 mm, with or without central hole are available.
- Materials: seamless mild steel pipe plus 95% alumina ceramics for liner
- Designed pressure: >= 0.35Mpa
- Normal operation velocity: 20-35m/s
- Normal operation temperature: -50-350
Running medium: mixture of air and powder
Size of the pipe: the inner diameter is between 1 to 120 and even lager
Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa.
Compression-shear strength is the bonding strength at the interface between the ceramic layer and the steel pipe. The compression-shear strength of the ceramic-lined composite pipe is 15 to 20MPa.
Resistance to Mechanical Shock
The ceramic layer does not crack or flake off when the composite pipe receives a mechanical shock.
Resistance to Thermal Shock
The ceramic layer does not crack or flake off when heated to 800℃ and then quenched.
Resistance to Abrasion:
The ceramic-lined steel composite pipe has exceptional resistance to abrasion. Its service life in materials transportation with hard abrasives is more than 20 times longer than in common steel pipe.
A composite elbow was used in a mining plant for about fifty thousands hours. The general service life of common steel elbow is about 700 hours.
The composite pipes have good corrosion-resistant. There is no evidence of corrosion filling the composite pipes with bitter for one year (left), but the common steel pipe under the same condition is corroded seriously (right).
